Sen. Mark Udall (D-Colo.), a member of the Senate Intelligence Committee, is placing a hold on the man nominated to become the Defense Department's top lawyer, his office confirmed to POLITICO.

President Barack Obama tapped Stephen Preston to become the Pentagon's general counsel; Preston currently serves as the CIA's top lawyer.

"Sen. Udall had some questions that had not been answered yet, so he placed a hold on Mr. Preston's nomination in order to allow more time to get some answers," Udall's communications director Mike Saccone told POLITICO.

Saccone would not provide details on those questions, but said they pertained to the Senate Intelligence Committee's report CIA's detention and interrogation program.

Preston was questioned by members of the committee on the report during his confirmation hearing.
